High quality BSCCO thin films have been fabricated by means of an ion beam sputtering at various substrate temperatures, T$sub$sub/, and ozone gas pressures, pO$_3$. The correlation diagrams of the BSCCOphases with T$sub$sub/ and pO$_3$ are established in the 2212 and 2223 phases come out as stable phases depending on T$sub$sub/ and pO$_3$. From these results, the thermodynamic evaluation of ΔH and ΔS, which are related with Gibbs` free energy change for single Bi2212 or Bi2223 phase, were performed.
